Sliding table for dinette....WoW

Hi, we have '91 Roadtrek and are luving it BUT..the table is difficult to get around to be seated. HOWEVER, I saw the greatest table in a used Leisure van. It has a slider on the bottom of the top that allows you to easily move it from side to side. This provides more than ample room to sit down and then, just a touch slides it back in place. Having had every camper type known to man except a 5th wheel, the majority had the same problem with dinette seating. The slider makes the problem GO AWAY. Does anyone know how I might be able to purchase or engineer (hubby) a reasonable replica?? I have searched all over www and can't find anything even similar. :shy:
